WILLIAM F. STRAUB, OF CHICAGO, ILLINOIS, ASSIGNOB TO ELECTRIC TIME RECORDER.` COMPANY, OF CHICAGO, ILLINOIS.

TIME-STAMP.

Specification of Letters Patent.

Patented Nov. 14, 1916.

To all whom it may concern Be it known that I, WILLIAM F. STRAUB, a citizen of the United States, residing at Chicago, in the county of Cool; and State of Illinois, have invented a. certain new and useful Improvement lin Time-Stamps, of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

My invention relates to time stamps and has for its object the provision of an improved arrangement for the controlling and stamping elements of the device together with improved constructional .features involving these setting and stamping portions. i

I will explain my invention more in detail by referring to the accompanying drawings illustrating one embodiment' thereof in which- Figure 1 is a front view partly in section of my improved time stamp; Fig. 2 is a side view partly in section of the same, and Fig. 3 is a detail of construction. i v

I utilize a suitable base plate 1 which is provided with the cup shaped recess 2 and on which a suitable cover plate 3 is mounted, which cover plate is provided with a slot 4 to permit the handle4 5 to pass therethrough, which 4handle is the one used to cause an'impression by the time stamp. The base plate has a depressed portion throughout the right half portion' of its upper surface (Fig.A 2) as shown more clearly at 6, and on top of this a plate 7 is placed which runs throughout the entire length of the top of the base and projects over at 8. A. small portion of this plate is cut-away as shown at 9 to permit all of the type wheels and the driving mechanism comprising the stamping device 10 to be depressed upon-the top ofthe base 1. It will be seen that there is thus provided a groove as shown atv 6 running entirely the length of the machine which is to accommodate the paper or card upon which the impression is to be made. The printing wheels of the stamping mechanism 10 are all to the right of the plate 7 so as to form the impression upon the paper inserted for receiving the impression.

The impressiomor stamping'device 10 togetherwith the various elements carrying the same and operated by the handle 5 are all mounted on a suitable plate 11 which is laid on top of the plate 7 and thenl fastened mea-ns of a spring 24 to a rocking arm in place through the agency of suitable screws not herein shown. This structure which is designed to cause periodic actuation of the impression device is similar in general arrangement to that disclosed inmy application Serial No. 735,718, filed Dec. 9,

1912. This structure including all this mechanism is mounted between two side walls 12 and 13- and includes a pair of toggle levers 14, 14 and 15, 15 at whose lower extremities the impression mecl ianism is pivotally carried. The handle 5 actuates this mechanism so as to depress the impression mechanism 10 to cause a rapid impression of the impression device which then recoils aultomaticallv so that this impressionv device cannot be held in its depressed condition. The lower extremities of the toggle members are held together by a shaft 16 and this is also mounted in and carried by a pair of arms 17 pivotally mounted on a shaft 18 fastened in the side members 12 and 13. The arms 17 are spanned by a bridge 19, which bridge normally rests on top of a cam 20 carried by the lever 21 which is fxedly secured to the handle 5. The upper extremity of the toggles'14, 14 are pivotally held upon a shaft 22 secured in the side members. The meeting extremities of the toggle members 14, 14 and 15, 15 are pivotally mounted upon a shaft 28. The shaft 23- is connected by 25 pivotally mounted upon the shaft 18. The arm 21 carries a pivotally mounted cam 26 which impinges against the arm 25 whenever the lever 5 is moved ina clockwise direction (Fig. 2). Whenever the movement of the arm 21 has progressed far enough, then the upper transverse extremity I274 of the arm 25 slides upwardly and over the top of this cam 26. Before the arm 25 however is released it has exerted a pull through the agency of the spring 24 upon the shaft 23, thus tending to move this-shaft 23th the right (Fig. 2), and thus depress the impresl sion dev ice 10. This however cannot occur asthe bridge 19 rests on the cam 2O until the Vsa Y arm 5 has been moved'far enough in a clocky wise direction to release the bridge 19, at

which time the spring 24 quick-ly draws the shaft 23 to the right (Fig. 2) and causesl an impression upon the card placed in the slot at 6. Immediately thereafter the extension 27 has `ridden over the cam 26, thus permitting the arm 25 to be pulled to the left (Fig.

2)y through the agency of the spring 24, thus to again permitthe shaft 23 to move to the left under the iniiuence of the lear" spring 28, Whenever the handle 5 is moved in a clockwise direction it also moves an arm 29 in a clockwise direction as soon as the arm 21 engages a pin 30 provided on the arm 29. This arm 29 through the agency of the spring 31, partly broken away 1n Fig. 2, acts on a lever 32, whicholever is pivoted to the arm 17 as shown in dotted' lines in F ig. 2. This arm 32 carries a cam shaped eXtremity 33 which is adapted to engage a star wheel 3.4 forming part of the type wheel mechanism, thus to accurately aline a type wheel that may not be in alinement, 'whenever the arm 5 is lirst moved to' cause an impression.

Movement of the arm 32 also causes a swinging movement of the arm 35 because this latter arm is connected by means of a link 36 to the arm 32. This arm 35 carries a roller 37 adapted to engage the star pinions 38 which serve to transmit the movement between the various type wheels. Thus whenever the arm 35 is so actuated to have its roll 37 engage the star wheels 38 as when an iinpres sion is being made, then the controlling mechanism which sets the typewheels is prevented from actuating said type wheels during the time that this impression is being made. A ribbon 39 is provided which is associated with two take up rolls 40 and 41 respectively, each provided with a ratchet'42, 43 respectively. The ribbon also passes about rollers 44, 45, 46 and 47, and thus is carried by under the type wheels as clearly apparent from Fig. 1.

Now whenever an impression is made a bell crank iever 48 is moved in a clockwise direction as its arm 49 is actuated between pins 50 and 51 provided upon the `arm 21. This lever 48 pulls a bar 52 downwardly, thereby actuating a lever 53 in a clockwise direction, this lever being pivoted vupon the stud 54. The movement of this lever through the agency of the stud 55 and slot 56 causes an up and down movement of a plate 57, which plate carries two pawls 58 and 59 respectively.' The pawl 59 is in F ig. 1 shown in engagement with the ratchet wheel 43. Now whenever this plate is moved downwardly the pawl 59 will engage the ratchet wheel 43 and move the take up roll.

41 the distance of one tooth. lt will be seen that the pawls are pivotally mounted on arms 60 and 61 respectively and are .either held in engagement with their respective ratchet wheels or away from them because the pawls are provided respectively with pins 62 and 63, which pins operate in slots 64 and 65 respectively. These slots are provided in a rocking;V bar 66 uivoted at 67, which rocking bar has acam 68. A plunger 69 pushed to the left bv the spring 70 is carried in another rocking bar 71, which nism to one side rocking bar 71 depends for its position upon the thickness of the ribbon upon either taire thickness that afre'versal of the parts is again effected, whereupon the roll 41 serves as the take up roll. l The impression mechanism 1s periodically and to withdraw pawl 59 from enset by rotating the shaft 72, which shaft then in the customary manner moves the type fi wheels. This shaft receives its motion from a pinion 73, which pinion through. the in terposition of pinions 74 and 75 receives i 1 movement from the gear wheel 76. 7 gear wheel 76 is fastened to a shaft 77, wi shaft carries two armatures '78 and 79, wbr armatures are under the infiuence of a e magnets 80 and cause a setting of these armatures onceper minute similarly to th" structure explained in my application Seriz No. 735,718. T mount this driving meehaof the operating device shown and thus obtain a very compact sim ple structure requiring very little internes diate mechanismdirectly from the shaft 7 7 to the time wheels. Parts of the mechanism. project inte the cup-shaped recess2 as isclearly apparent from an inspection ofFig. 1. wo gear wheels 74 and 7 5 are interposed between the gear wheel 76 and the gear wheel 73 so -to avoid movement of the shaft 72 whenever the impression mechanism is actuated as wili be clear from the illustrations, as only the gear wheels 74 and 75 need turn9 thuspen 1;'

mitting the gear wheel 73 to remain sta tionary except when operated by the driving gear 76.

I have thus described one 'crm' which my invention may takeand it will be readily apparent that many modiiications may be made without .departing from the spirit of my said invention. y Havinghowever thus described one form which my invention may take, what l claim as new and desire to secure by `Letters Patent is: c l
